Selecting suitablely the shrink range between two rings can effectively decrease stress and factor of stress concentration, and increase anti-fatigue strength of stuffing box.
The Fig.3b describes mechanical model of thick-walled tune.
Surface of test points should be polished by electrolysis to required depth because residual stress test required removing processing stress on the stuffing box. 3.1.2 Residual stress test scheme In order to determine the residual stress on the surface of stuffing box affected by interference structure and process, the measurement procedure can be summarized as follows: (1) Total residual stresses of the stuffing box as a combined tune were examined, mainly caused by interference structure and other factors; (2) Residual stresses were measured again, excluding influence of interference structure after two rings were separated in freedom.

Obviously, such a large difference would lead to inhomogeneous mechanical properties, dislocation block, and stress concentration.

The wiper motor installed on the front windshield and worm gears are generally made of one mechanical part.
Wiper motor is very high quality requirements and DC permanent magnet motor is adopted, wiper motor installed on the front windshield and worm gears are generally made of one mechanical part.
In optimization on the windscreen wiper mechanism, the objective function is the most important factor, as it not only influence design scheme quality, also can affect the design course.
Instead, a penalty factor was applied to each design if the constraints were violated.
The fitness function is： [ ]{ } 2 6 1 ( ) ( ) max 0, ( )i i x f x R g x ϕ = = + ∑ ，where R-penalty factor，R=28000.

From the view of the business processes based on O2O, customers, stores and website platform are indispensable key factors of O2O, so the key point of O2O is to satisfy the value of customers, businesses and platforms.

However, stainless steels are still most frequently used metallic materials for internal fracture fixation devices [1 - 3] because of the favourable combination of mechanical properties, acceptable biocompatibility and cost effectiveness compared to other metallic implant materials [1, 2].
HE process a) scheme; b) deformation zone [5] It has frequently been reported, that the nano-metals obtained by SPD, including thosed processed by HE, exhibit improved mechanical properties.
However, the effect of SPD on other physical and chemical properties of processed materials, such as corrosion resistance is less understood [6].
Any heterogeneities, such as inclusions, affect the quality of the passive layer and are possible sites for the initiation of corrosion.
In order to identify the factors responsible for the corrosion resistance of 316LVM, the residual stresses in the as-received and HE material were measured by the XRD method using the Cr Kα radiation and calculated using the widely known sin 2ψ method [13] for the set of planes {211}.

The new grinding wheel was compared with conventional grinding wheels by comparing the factors of grinding performance, such as surface roughness, morphology, wheel wear ratio, grinding temperature, and grinding forces, when the wheels were used under two different coolant strategies—dry and with minimum quantity lubrication (MQL) using pure water.
Before machining, the test materials were premachined with a 1 mm cut to remove any possible surface irregularities and ensure similar surface properties for all the specimens.
Plot of (a) tangential forces and (b) normal forces versus depth of cut It is well known that surface roughness can significantly affect the mechanical strength of components when they are subjected to fatigue cycles.

At the same time the hair moment of inertia is of order O(d2), negatively affecting the resonance frequency (i.e. bandwidth).
For the crickets the hair-sockets provide some torsional damping (R) by visco-elastic material properties (see [12] for such material properties in spider hair mechano sensors) whereas for the artificial hair-sensors torsional damping is caused by both material as well as squeeze film damping due to the small gap between the siliconnitride plates and the substrate.
However, with respect to damping the optimum damping factors still need to be identified.
Using optical read-out it was possible to improve the detection limit by a factor of ≈ 25 times [13].

These structural parameters have mainly positive influence on important mechanical properties of superalloys.
Solid solution provides fundamental strength characteristics of superalloys (tensile strength, fatigue properties, creep resistance, and hot-corrosion resistance) [6].
Unique properties of superalloys are close related to fraction of γ'-phase.
For example, coarse γ'-phase means decreasing of mechanical properties due to easier slip of dislocations.
Metallography is a powerful tool at fatigue failure mechanism description and provides information how microstructure is related to mechanical properties.

These factors have to be considered as virtually non-suggestible but their affecting during the adhesive bonding application is relatively significant [5].
Thus, the adhesive bond is not supposed to maintain its properties during the whole time of moral and physical lifetime of the bonded set.
Gerald, Pethrick [7] declare that the environment changes can influence both the way which modifies the adhesive physical properties in time and the strength of the interface adhesive – adherent.
Degradation processes affecting the adhesive bonds were continuously evaluated after passing set time intervals – 2, 4, 8, 16 and 32 weeks.

The result shows that the width of the sealing surface and the contact stress altered with the change of structural parameters, which affected the sealing most.
So the leakage rate can be deduced as follows: (5) Considering the relationship between H and h is as follows: (6) where is the average stress on the sealing surface, is a sealing factor of the cone material.
So conclusion can be drawn that the seal property is the best when the cone angle is 24 degrees.
